z NH

wherein R R R and R each independently represent a member selected from the group consisting of hydrogen. halogen. lower alkyl having l-4 carbon atoms and lower alkoxy having [-4 carbon atoms; R represents a member selected from the group consisting of hydrogen. lower alkyl containing 1-4 carbon atoms and lower alkyl having l-4 carbon atoms and substituted with a member selected from the group consisting of hydroxyl and wherein R and R; each independently represent a member selected from the group consisting of hydrogen, lower alkyl having l-4 carbon atoms and lower alkyl having l4 carbon atoms and substituted by a member selected from the group consisting of hydroxyl. carbamyl. acylamino wherein acyl has the meaning given above. mesylamino and benzoylamino, and

wherein n represents 2-6, preferably 2, and R and R each independently represent a member selected from the group consisting of lower alkyl having 1-4 carbon atoms. lower alkyl having 1-4 carbon atoms and substituted by a member selected from the group consisting of hydroxyl and acylamino wherein acyl has the meaning given above. and R and R together with the nitrogen atom to which they are attached form a sixmembered heterocycle capable of including an oxygen heteroatom. such as piperidinyl or morpholinyl.

The present invention also relates to the salts of the compounds of formula I with mineral or organic acids such as the hydrochloride. hydrobromide. and sulfate thereof and to the quaternary ammonium salts of those compounds which have a tertiary amino group.

The compounds of the present invention can be prepared by condensing a 3-amino-4-methoxy phenol of the formula wherein R has the meaning given above or on a salt of said compound formed with a mineral or organic acid. on a member selected from the group consisting of a. a compound of the formula wherein Z, R,. R R and R have the meanings given above. or a salt of said compound. the molar ratio of compounds Ill/II being preferably between 0.75-1.75. the condensation being carried out at a temperature between 5-40 C at atmospheric pressure;

b. a benzoquinone-monoimine or diimine of the formula:

2' \J 1 2 (IV) KLRI wherein Z represents a member selected from the group consisting of oxygen or imine and R R R and R have the meanings given above with the proviso that at least two of R,. R R and R are other than hydrogen. The condensation is carried out. preferably, at a temperature betwen 540 C. at atmospheric pressure. The molar ratio of compound IV/II is preferably equal to l; and

c. a nitroso derivative of the formula:

(v) R R or a salt thereof. wherein Z. R,. R R and R have the meanings given above. the condensation being carried out. preferably. at a temperature between lS-80 C. at atmospheric pressure. the molar ratio of compounds V/ll being between 1-1.5.

The condensation of compounds 1]] or IV on compound II is carried out in an aqueous. hydroacetonic or hydroalcoholie medium at a pH made alkaline by the addition thereto of. for example. ammonia. and in the presence of a large excess of H 0 -75% H 0 volumes). compounds lll. 1V and II generally being used in equimolar amounts.

The condensation of compound V on compound ll is carried out in an aqueous. hydroalcoholic (the proportion of alcohol varying between O-lOUVr or hydroacetonic (the proportion of acetone being between 050% medium. or even in absolute ethyl alcohol. es pecially when compound I is isolated in salt form. Compounds V and II are preferably employed in equimolar amounts and the pH of the reaction medium can either be made alkaline by the addition thereto of ammonia. or made slightly acid by the addition thereto of acetic acid. It will be noted that the reaction medium itself is acidic when the compound used is a hydrochloride. hydrobromide or sulfate of compound V and thus the addition of acid to the reaction medium in this case would generally be superfluous.

The condensation of compound V on compound II is generally carried out in the presence of H 0 However. the presence of H 0 is not necessary in certain instances. particularly when the reaction is carried out in absolute ethyl alcohol and when the compound V utilized is in the form of a salt thereof. The amount of H 0; (20 volumes) employed can vary between 0-75 percent by weight of the reaction mixture.

When compound I carries a quatemizable tertiary amine function the quaternary amine of this compound can be prepared by reacting it with an alkylating agent such as methyl or ethyl sulfate.'methyl or ethyl iodide or bromide. or benzylchloride. The quaternization reaction can be carried out at ambient temperature in an appropriate solvent such as dioxane or a mixture of dioxane and ethanol.

The compounds of the present invention are usefully employed as dyes which exhibit good affinity for keratinic fibers. particularly human hair.

It is known. for instance, that many dyes for coloring hair often impart to the same a reddish glint or hue which is not always desirable. The present invention however provides a solution to this problem. The diamino benzoquinones of the present invention impart to keratinic fibers a wide range of green glints which diminish or suppress the red glints or highlights of conventional eolorations, particularly red hair.

Diaminobenzoquinones. generally, are already known. Thus. US. Pat. No. 2.267.74l and FrenchJat. No. 847.026 describe diamino benzo l.4-quinone of the formula I HN O NH 0 l wherein X and Y can represent hydrogen; and R, and R different from one another. can be hydrogen. alkyl or aryl. These compounds are dyes which dye wool yellow. brown or red-brown and are not suitable for the present purposes.

German Pat. No. 300.706 describes some monoaryl and diaryl aminoquinones which dye wool yellow or brown. These compounds also are not suitable for the present purposes.

French Pat. No. l.554.722 describes aminoquinones that are used as antioxidants for a lubricant, rubber and plastic material.

The present invention also relates to a new industrial product comprising a dye composition for keratinic fibers. particularly human hair. comprising a solution of at least one compound of formula I or a salt thereof or a quaternary ammonium derivative thereof.

The compositions of the present invention are aqueous solutions which can also include one or more low molecular weight alcohols. such as ethanol or isopropanol, or one or more glycols. such as butylglycol or propylene glycol. so as to facilitate the dissolution of the dye in the water. The amount of alcohol can vary. for instance. between about 5-70 weight percent of the composition while the amount of glycol can vary generally between about 2-5 weight percent of said composition.

The concentration of the compounds of formula I. or their salts, in the dye compositions of this invention can range between about 0005-05. and preferably between about 0.005-0.25. percent by weight of said composition.

The pH of the compositions of this invention can vary between about 4-1 1. the compounds of formula I and their salts, exhibiting strong dyeing power in this extensive pH range. The pH of the compositions can be adjusted to the desired value by the addition thereto of pH adjusting agents conventionally employed in cosmetic compositions such as. for instance. an acid including for example orthophosphoric acid. lactic acid or acetic acid. or a base such as ammonia or triethanolamine.

The compositions of the present invention can include as the dye component only the compounds of formula l. or salts thereof, in which case they provide a wide range of very luminous green solutions rich in metallic glints, ranging from silvery almond green to very dark green, passing through light bronze. ash blonds and linden colors with golden glints.

The compositions of the present invention can. however. include other direct dyes. for example. azo dyes. anthraquinone dyes, nitro dyes of the benzene series. indophenols, indoanilines. indamines or oxazines. The present composition can also include oxidation dyes such as dior tri-amino phenols or amino diphenols.

Further. the compositions of the present invention can also include adjuvants conventionally employed in cosmetic compositions such as wetting agents. emollients or perfumes. The compositions can also be packaged under pressure in aerosol containers with a conventional liquefied aerosol propellant such as a fluoronated hydrocarbon including dichlorodifluoromethane. trichloromonofluoromethane and mixtures thereof. and other halogeneted hydrocarbons.

The compositions of the present invention. in one embodiment. can be employed to provide durable hair colorations. [n this embodiment the compositions are applied to the hair for a period ranging from about -13 minutes. the thus-treated hair thereafter being rinsed. washed and dried.

The present compositions can also be employed as a hair rinse lotion for use in imparting to the hair a slight coloration. in this embodiment the compositions are 1 applied to washed hair, which application is not followed by any rinsing operation.

Further, the compositions of the present invention can be used as a hair setting lotion to impart a slight coloration to the hair and to improve the holding power of the set. In this embodiment. the compositions comprise a hydroalcoholic solution of the dye component in combination with at least one cosmetic film-forming resin. The hair setting lotion is applied to previously washed and rinsed wet hair, followed by rolling the hair up on curlers and drying the hair.

Representative cosmetic film-forming resins usefully employed in the hair setting lotions of this invention include polyvinylpyrrolidone, having a molecular weight between 40,000 and 400,000; copolymers of vinyl-pyrrolidone and vinyl acetate (70-30:30707c); copolymers of vinyl acetate and an unsaturated carboxylic acid such as crotonic acid (90:10) having a molecular weight of about 20,000-50,000; copolymers resulting from the copolymerization of vinyl acetate (75-85%). crotonic acid (5-1872) and an acrylic or methacrylic ester (5-157c), copolymers resulting from the copolymerization of vinyl acetate and an alkyl vinyl ether, copolymers resulting from the copolymerization of vinyl acetate (63-88%), crotonic acid (5-l57c) and a vinyl ester (5-25%) of a long carbon chain acid (10-22 carbon atoms) or an allyl or methallyl ester of a long carbon chain acid 10-22 carbon atoms), copolymers resulting from the copolymerization of 65-80% ester of an unsaturated alcohol (2-12 carbon atoms) and a short carbon chain acid (2-5 carbon atoms) or a 7-127: unsaturated short chain acid (4-20 carbon atoms) and 10-20% at least one ester of a saturated short chain alcohol (8-18 carbon atoms) and an unsaturated acid (4-20 carbon atoms) and copolymers resulting from the copolyme rization of at least one unsaturated ester at at least one unsaturated acid.

The preferred cosmetic film forming resins include polyvinylpyrrolidone, copolymers of crotonic acid and vinyl acetate. copolymers of vinylpyrrolidone and vinyl acetate, copolymers of maleic anhydride and butyl vinyl ether, terpolymers of methyl methacrylate-stearyl methacrylate-dimethyl methacrylate; and terpolymers of vinyl acetate-ally] stearate and allyloxy-acetic acid.

The cosmetic film forming resin is generally present in amounts of about 1-3 percent by weight of the total composition.

The alcohols conveniently employed toproduce the hair setting lotions according to the present invention are low molecular weight alcohols, preferably. ethanol or isopropanol. which are present in amounts generally of about -70 percent by weight of said composition.

The following examples are given to illustrate the invention. 1n the examples an ethyl alcohol at 96 corresponds to 950.189 g/kg of alcohol.
